For the purpose that you describe, I think that it is not so
complicated. You should certainly not hand-edit each image, but do it
with some scriptable tool. For example the ImageMagick set can add
text to an image or superimpose two images (one molecule image and one
label image) and can do the same operation to a set of files.

If the labels are supposed to stay fixed for the whole duration of the
movie, you could also use the Logo feature in VirtualDub
(http://www.virtualdub.org) to superimpose a premade image to each
movie frame - this supposes that from the individual images you
generate an AVI file, as VirtualDub doesn't deal with other movie
formats.
